Several questions about settings and behavior of new Biotronik Edora 6 DR-T
Hi everyone, my first post! I had a Biotronik Edora 6 DR-T implanted about a week ago for sick sinus syndrome, and would appreciate any information or advice on the following.
* Can this device be causing PVCs or possibly bouts of tachycardia? Or may I be mistaking the PM's activities for these? Over the first few days, I had a lot of what felt like PVCs, sometimes for runs of 5-15 beats, though this calmed down in the next few days. I've had PVCs before (Dr. said not dangerous), but it was never anywhere near this number or frequency. Does the PM detect, prevent, or otherwise affect PVCs? The reason I doubt it's the PM directly is that these runs tend to start suddently (and without any obvious reason), and stop just as abruptly.
* Is the rate adjusting algorithim a bit trigger happy? Tracking my heart rate over nights, I can see that it's 55 BPM when resting VERY QUIETLY in bed (min rate set to 55), but any movement or sitting up will jump it to 75 BPM very quickly, and if I get up for a bathroom break it will quickly go to 90BPM. (FYI CLS - Closed Loop Stimulation - is turned on.)
* What's a normal decay rate once the PM ups the BPM? It seems to take 3-5 minutes for it to settle back down to the 55-60 BPM range after spiking to 90 or so when I get up and move around. My "old" heart would return to my natural base rate (35-40 BPM) much quicker, but perhaps that's not normal.
* Despite all this, when exercising (stationary bike) I can only get my heart rate up to about 115 BPM max, which is about the same as before the PM. My max rate is supposedly set to 130 BPM, but I can't seem to figure out how to get it there. Do I need to try some other form of exercise that will cause the accelerometer to trigger more? Jumping jacks? ;)
* The "CardioMessenger Smart" monitoring device supposedly transmits a daily report to ... someone somewhere. It's not plausible that my cardiologist at Kaiser Northern CA reads daily reports from all his patients. Practically speaking, how is this handled?
* Do the reports include any measures of unusual events, such as excessive PVCs or tachachardia? Will it flag any arrythmia problems, like those noted above?
* Is it possible for a patient (me) to get copied on the reports, or is this a "professionals only" thing?
* This may be a conicidence or my imagination, but around 2AM every night I get woken up by some unusual heart activity, I suspect the PM may be doing some nightly testing? If so, can I get this reduced in frequency to say once a week, and perhaps moved to 8AM when it would be less disruptive (and I can anticipate it)?
* Since the PM can be set for both day and night rates, it stands to reason that it contains a clock. (Mine is set to a min rate of 55 BPM for both day and night.) Digital clocks tend to drift, though most "internet connected" devices will read the time and reset themselves periodically. Is the PM clock adjusted nightly when talking to the CardioMessenger Smart, only when programmed, or never? What happens when I travel to a distant time zone, does this adjust in any way?
* I've read a lot of conflicting info about interference, mainly from magnets and EMI. My PM is supposed to be MRI safe, but what's the "failure mode" in these cases, i.e. does the PM stop working temporarily, revert to the minimum BPM, etc.?
Thanks for any help or advice!
